Description

?

MF Series modular self-cleaning filter (MF Filter for short) is the automatic filtration system designed by LIVIC according to the modular design concept. It has the high reliability and flexibility for expanding. It has the following features: running automatically, very durable, no manual cleaning, very easy to open for maintenance, with unique V-SLOT filter element, completely back-flushed and less back-flushing discharging liquid. MF filter can purify the liquid and protect the downstream key equipments. It is designed and manufactured by the high performance, high quality, high reliability standard of LIVIC and has the world class quality.

?

MFR filter and MFV filter are applied between the filtration degree from 20-500 micron, for the water and low viscous liquids. They are good at filtering the micro fibers, oil-mud and soft impurities, which ordinary self-cleaning filters can hardly work. MFT filter and MFG filter , as the manual filters, are only for liquids with less impurity content and easy to back-flush. They are for applications with less back-flushing frequence. LIVIC is the world leading self-cleaning filter manufacturer with the full series self-cleaning filters, which can meet the customers& acute; various filtration demands.

Tubular Filter MF Custom-made option

?

MF filter provides custom-made options to meet the customers& acute; demand better:
■ High temperature design with high temperature resistance sealing and fluid control valves
■ Filter element with larger filter area design; sintered multi-layer mesh filter element
■ Ex-proof design including the valves, control system to filter the inflammable and explosive liquids
■ All valves with the position switches, which provide the error feedback function

?

Applications:

?

■ Applicable Industries: raw water treatment, water treatment system, cooling system, power generation, steel mill, pulp and paper, mining, petrol-chemical, municipal facility, etc.

■ Applicable liquid types: raw water, process water, clean white water, super clean water, circulating cooling water, high pressure spraying water, low pressure spraying water, sealing water, squirt cut water, etc.. Various raw oils like diesel, gasoline, naphtha, residual oil; hot rolling coolant or cold rolling coolant in the steel mill

?

Technical Features and Advantages

?

■ Only one extra filter module as the spare for the whole system, low breakdown risk, less investment cost

■ The filter modules can be switched off-line and manual cleaned one by one with no filtering interruption.

■ It only takes 5 seconds to open the filter module& acute;s lid. Very easy to pull the filter element out and low operation cost.

■ When filtering some difficult impurities and periodic manual cleaning is necessary, it is the best solution

■ Back-flush by the valve switching, no complicated mechanic structure, very easy for maintenance.

■ Continuously filtering when back-flushing, no systen downtime and downtime cost.

■ Modular combination, easy for expansion, increase the flowing capacity by adding several more filter modules

■ With V-SLOT slotted filter element, easy to clean completely, extreamly durable and long service life.?

■ MFV filter applies to the filtration before the pump or with very low inlet pressure by external fluid back-flushing

■ Modular combination with high quality ball valves, instruments and control system of high reliability
